E - the type of the List elementspublic abstract class ListPropertyBase<E> extends ListProperty<E>
ListPropertyBase is the base class for a property
wrapping an ObservableList.
It provides all the functionality required for a property except for the
ReadOnlyProperty.getBean() and ReadOnlyProperty.getName() methods, which must be implemented
by extending classes.ObservableList,

| Modifier and Type | Method and Description |
|---|---|
void |
addListener(ChangeListener<? super ObservableList<E>> listener)
Adds a
ChangeListener which will be notified whenever the value
of the ObservableValue changes. |
void |
addListener(InvalidationListener listener)
Adds an
InvalidationListener which will be notified whenever the
Observable becomes invalid. |

addListener(ListChangeListener<? super E> listener)
Add a listener to this observable list.
|
void |
bind(ObservableValue<? extends ObservableList<E>> observable)
Create a unidirection binding for this
Property. |

A boolean property that is
true, if the list is empty. |

get()
Get the wrapped value.
|
protected void |

The method
invalidated() can be overridden to receive
invalidation notifications. |

isBound()
Can be used to check, if a
Property is bound. |
void |
removeListener(ChangeListener<? super ObservableList<E>> listener)
Removes the given listener from the list of listeners, that are notified
whenever the value of the
ObservableValue changes. |
void |
removeListener(InvalidationListener listener)
Removes the given listener from the list of listeners, that are notified
whenever the value of the
Observable becomes invalid. |
void |
removeListener(ListChangeListener<? super E> listener)
Tries to removed a listener from this observable list.

ObservableInvalidationListener which will be notified whenever the
Observable becomes invalid. If the same
listener is added more than once, then it will be notified more than
once. That is, no check is made to ensure uniqueness.
Note that the same actual InvalidationListener instance may be
safely registered for different Observables.
The Observable stores a strong reference to the listener
which will prevent the listener from being garbage collected and may
result in a memory leak. It is recommended to either unregister a
listener by calling removeListener after use or to use an instance of
WeakInvalidationListener avoid this situation.

If the given listener has not been previously registered (i.e. it was never added) then this method call is a no-op. If it had been previously added then it will be removed. If it had been added more than once, then only the first occurrence will be removed.

ObservableValueChangeListener which will be notified whenever the value
of the ObservableValue changes. If the same listener is added

check is made to ensure uniqueness.
Note that the same actual ChangeListener instance may be safely
registered for different ObservableValues.

InvalidationListeners,
ChangeListeners, and
ListChangeListener.
This method is called when the value is changed, either manually by
calling set(ObservableList) or in case of a bound property, if the
binding becomes invalid.protected void fireValueChangedEvent(ListChangeListener.Change<? extends E> change)
InvalidationListeners,
ChangeListeners, and
ListChangeListener.
This method is called when the content of the list changes.change - the change that needs to be propagatedprotected void invalidated()
invalidated() can be overridden to receive
invalidation notifications. This is the preferred option in
Objects defining the property, because it requires less memory.
